I hate to say this, but seeing how it doesn't look like you boost, you aren't losing anything. I would retire and start fresh. He's not all that terrible, but he is from season 2 and only has a couple years left anyway, why not do him right.
Thank you for the advice, I figured as much. No, I don't usually boost, though I am slowly figuring out that this game is angling more and more towards requiring us to boost to be successful, which is understandable since Bort wants money. This player is on a Casual team right now, I'll give him the axe at season's end!
